This cooler has been in my family for as long as I can remember, and recently recieved it for a gift. Fairly soon, I plan on re-upholstering the lid. Otherwise it is really neat with all the plastic, including the drain, and bottle openers built into the handles.
Being from Wisconsin, and the fact that it's been around me for so long, it's something that I would never sell, but am still curious what they are worth. I've heard from $50-$100.
